Definitions
- the invention relates to a liquid filter, in particular water filter for swimming pools or the like, consisting of a closed container with a liquid inlet and a liquid outlet, between which at least one filter body or at least one filter material bed is arranged.
- Coarse impurities, turbid substances, colloidal substances and microorganisms get into the pool water. Filtration, for example with sand, anthracite, dolomite, lava gravel, silicates or activated carbon, can hold back coarse impurities and turbid substances. In order to convert the colloidal as well as some of the really dissolved substances into a filterable form, some flocculants are used, which are also separated in filters.
- certain layer heights of the filter material must be specified or provided accordingly, e.g. with sand as filter material, a layer height of more than 1.2 m with closed filter housings.
- the liquid filters known according to the prior art consist of two half-shells which are held by a clamping ring. Water is pumped via a liquid inlet and a liquid outlet through a pipe system of the container which is filled with gravel or sand or similar filter media for filtration.
- the entire inner tube structure and the holder elements for screens or the like are very complex.
- the simplification of the structure is intended to enable less expensive production.
- the liquid filter according to claim 1 which according to the invention is characterized in that a channel connected to the liquid inlet and having an outlet opening in the upper region is arranged on the inner wall of the container.
- the connection of the above-mentioned channel to the inner wall of the container can preferably be carried out in a material-saving manner and also make additional holders or pipes unnecessary. It is impossible to kink the water supply channel if the cover is opened carelessly, since the cover for the water supply is also removed with the cover. The manufacture can be made considerably cheaper, particularly in the case of a one-piece construction.
- the water discharge channel can also be designed as a second channel with an inlet opening in the lower container area as a connection to the liquid outlet.
- the channel or channels consist of two walls parallel to one another and perpendicular to the inner wall of the container and a cover essentially parallel to the inner wall of the container. This cover is detachably connected to the parallel walls of the channel.
- the container can consist of an upper and lower part releasably connected to one another via a clamping ring, at least one of which is a plastic injection molded part, which is preferably produced in one piece with the channel walls.
- the cover for example in the form of a strip, can be clamped onto the parallel side walls, screwed on or attached with the connecting means customary according to the prior art.
- the liquid inlet and the liquid outlet are preferably arranged in the lower part of the container, the end face of the upwardly leading first channel of the lower part connected to the liquid inlet abutting the end face of the channel of the upper part. If necessary, relevant channel sections can interlock if an improvement of the seal to the outside or to the interior of the container is desired.
- the first channel in the upper part is provided at its liquid outlet end with a cover which has bores, slots or other openings.
- the cover is an annular liquid distributor that allows the liquid to drain onto the sand and / or gravel fill.
- In the lower area there is a finely slotted cover on the inlet opening, which is intended to prevent filter material from being discharged through the drain.
- the cover of the first and / or the second channel can be fastened by means of a clamp, snap or screw closure, so that they are accessible for maintenance work or for any exchange.
- the layer height is achieved by a liquid guide which also has deflections between the water inlet and the water outlet. These liquid deflections can be 180 ° deflections, so that the liquid is guided in opposite directions in adjacent chambers, but they can also consist of a helical or spiral-shaped liquid guide.
- the height can be halved simply by using two adjacent chambers, which are connected to each other by a 180 "liquid deflection. At least two adjacent chambers are preferably provided, which can be flowed through with oppositely directed currents. If there are n adjacent chambers, the overall height increases 1 / n shortened.
- feedthroughs to the adjacent chamber are preferably used in the respective chamber floor or in the vicinity thereof, in order to obtain the most space-saving design.
- the chambers are preferably arranged essentially vertically next to one another, wherein according to a further embodiment of the invention at least one of the chambers is arranged concentrically to another chamber and is designed as an annular chamber.
- a central, cylindrical chamber with a plurality of further annular chambers surrounding it at different radial distances can be provided in this construction.
- These chambers are connected to one another by respective side wall and / or bottom openings, 180 "pipe elbows and / or overflows, in particular in such a way that two adjacent chambers have a common cylindrical wall.
- the liquid introduced through the water inlet is introduced into the upper region of one of the outer annular chambers, where it sinks downwards, according to the principle of the communicating tubes in the chamber Riser pipe rises accordingly and is discharged through a water outlet located deeper than the water inlet.
- a fabric filter is arranged between the part of the riser filled in the filter bed and the water outlet.
- This fabric filter preferably consists of a closed ring Composite filter fabric, which is clamped between a closed lid and a bottom with an opening (to the riser pipe).
- the filter belt is clamped in a wave-like or zigzag shape running between the cover and the bottom, so that there is an enlarged passage area for the water.
- a fabric filter is described, for example, in EP 0 071 200 B1.
- a pipe connected to a water inlet connection leads to a distributor arranged in the upper container space, through which the liquid is distributed into an outer annular chamber.
- a distributor arranged in the upper container space, through which the liquid is distributed into an outer annular chamber.
- the riser pipe connected to the outer ring chamber is arranged, at the upper end of which an outlet pipe is arranged as a connection to the outlet port.
- the container is formed in two parts, the container parts being releasably connected to one another.
- the interior of the container is easily accessible when changing the filter material or for other work.
- One of the container parts is preferably a removable cover.
- the liquid filter shown in FIG. 1 consists of injection-molded parts, namely an upper part 10 and a lower part 11, which are held together by a clamping ring 12.
- the lower part 11 has an inlet 13 and an outlet 14 which lead via a wall opening to respective channels 101 and 102, which in the simplest case consist of two parallel side walls perpendicular to the inside wall of the container and a cover lying parallel to the inside wall of the container, which cover is clamped or screwed on.
- the channel 101 connected to the liquid inlet 13 has a lower end 103, so that pumped-in water flows upward in the channel.
- the channel 101 ends in the upper container area and is connected to a cover as a distributor 16. This cover can have slits, openings or similar water-permeable geometries.
- a bed of gravel and / or sand is built up in the container interior 104, which serves as filter material.
- the channel 102 is shielded from the passage of filter material into the channel 102 by a cover provided with slots, bores or other openings.
- the channel 102 which is constructed like the channel 101, is delimited at the top by a separation 103. The flow of liquid is shown schematically using arrows.
- FIG. 2 A further embodiment is shown in FIG. 2, which likewise consists of a cover 10 and a base part 11, which have a circular cross section and are detachably placed on top of one another, with outer ring beads being fixed in each case with a clamping ring 12 at the attachment point.
- a riser pipe 20 is provided in the center, around which a sand or other filter bed is arranged in the annular space. Via the cover 16 provided with throughflow openings, the liquid to be filtered passes into a further annular space 104, which can be filled, for example, with activated carbon or other filter cartridges.
- a fabric filter consisting of a bottom 23 provided with an opening and a cover 24 as well as filter fabric 25 clamped between the bottom and the cover.
- the water can flow into the cylinder interior formed thereby via this filter fabric and flow downwards in a centrally arranged tube 26 in order to get from there into the annular channel 102 to the liquid outlet connection 14.
- the advantage of this arrangement is that the height of the filter container is minimized by half by deflecting or guiding the water in a riser pipe.
- the liquid filter shown in FIG. 3 corresponds in its outer structure to the liquid filter shown for example in FIG. 1 and previously described. However, in addition to a gravel fill, activated carbon cartridges 30 with an inside downpipe 31 are located in the container interior 104, via which liquid flowing out there arrives in the outlet channel 102.
